Hhmmm, seeing any of the recovery POST codes is not a good sign. Since you last saw POST code 34 (Loading Recovery Capsule), it may be that the BIOS Flash IC has failed.This may be nonrecoverable.
- Did you try jumper in maintenance position? See if this lets you get into BIOS Setup (unlikely but worth trying).
- Did you disconnect power (unplug from wall) when you pulled the battery? If not, do so - and leave the battery out for at least an hour (some CMOS parts stubbornly hold onto their values for longer than others).
- I know you said you pulled everything but CPU & RAM, but I have to ask: Did you actually pull the video card? If not, try this (it is possible problem is with Video BIOS Option ROM on card).
Hope this helps...
Thank you for your reply.
- I had tried maintenance mode. But same thing happens.
- Yes, i did unplug from wall when i removed battery. As per your suggestion i also pulled the battery for more than an hour but not difference. But one thing i noticed is that many times when the system starts, -- is shown on the debug card instead of any POST code. Sometimes it shows the same 34. Also, if i pull out the jumper with .bio in DVD, the post code shows 28 for few seconds and then it turns 34. So memory test completed and then it shows 28, then gets stuck at that for a minute or so, then restarts. This process continues for as long as i let it run.
- There is no video card. I have always been using on-board graphics.
